12, Bell Street

12 Bell Street is an early 19th-century building that stands three stories tall. Its elevation matches that of No 10 but features a separate slate roof and flanking chimneys. The façade is made of painted brick and includes a dentil cornice. There are three window bays: on the second floor, there are three square sash windows with architrave frames and glazing bars. The first floor has flat-headed sash windows set within segmental arches, although the glazing bars are missing.

The ground floor features a 19th-century shop front with two windows, each consisting of three lights, where the innermost light on either side angles towards the central doorway. The lights have shallow elliptical heads, and there is an original glazed door with a similarly shaped fanlight above. A fascia with a fine dentilled cornice is positioned above, featuring a small moulded hood on shaped brackets, although the stall-riser has been modernized. The doorway at the northern end is flanked by fluted pilasters, with a moulded panel and foliated brackets above, topped by a small moulded flat hood. Behind the doorway is a three-panelled door, with the upper two panels being glazed.

Nos 10 and 12 Bell Street, along with No 1 Corn Market, form a cohesive group.
